Conclusion

The MMSWF prototype worked properly based on the defined features.

The developed prototype is portable and low-cost working prototype

The water filter was also able to remove impurities such as dirt and other solid particles during the filtration.

The pH sensor was able to get the input and output value of the water before and after the filtration process.

The researchers were able to compare the input and output value of the pH MMSWF and the digital pH meter.

Recommendations

Include a BioSentry sensor, which detects bacteria and other filthy organisms.

If implemented, MMSWF should also have a UV purifier for killing the bacteria.

Add volumetric and Time monitoring Features.

Use MMSWF in a place where the temperature will not exceed 30 degrees Celsius.

Limit the usage of the filter up to 2 L of contaminated water only.

To assure the quality of water, use only water that is stored in closed barrels and avoid using unsecured containers.
